Deepak Chopra on the Effects of Stress
But stress is bad for you in far more basic ways. The hormones that are released in the body’s stress response, such as cortisol and adrenaline, are meant to be temporary. Their effect is to galvanize the fight-or-flight response, which is triggered in a primitive area of the brain, because fight-or-flight is an inheritance from our pre-human past. In the stress response, a privileged pathway is opened for dealing with emergencies, while at the same time the brain’s higher responses are temporarily suppressed.
